I know where you are coming from OP. I use a Mac, and I like to play games. I don’t see the point of having a desktop PC for games, and I truly love the aesthetics, beauty, and overall design of Macs. I personally do not believe that it is insane to purchase a Mac to play games, whether you use it for other tasks or you bought it solely for that. It is your money, it is your life, don’t let peoples definition of what makes sense in a particular situation to them necessarily apply to you. Is it going to be even more difficult now with Apple Silicon? Yes. Is it impossible? No, not at all. In fact, ever since the Developer Transition Kit I have been testing the gaming performance of the A12Z to see how well it could even run games in the Mac App Store (i.e. Tomb Raider) when it wasn’t even supported. It ran surprisingly well.
Then M1 came out and Bootcamp was officially dead for Apple Silicon users. I tinkered around with solutions on github to load up ARM Windows prior to Parallel officially releasing their Technical Preview. I went through my Steam library of about 25 games to see what worked and what didn’t. I reported my findings to a Reddit user who collated mine and others sources of games that worked on Apple Silicon.
Apple Silicon has now matured even more. In Parallels official release supporting Apple Silicon, it was jaw-dropping to see how well games worked in a virtualized environment with an 8GB Unified Memory machine on the M1. Now with M1 Max coming out next week, I am going to continue playing games on a Mac, now with 64GB Unified Memory and a 32-core GPU. Do I work on my Mac? Yes. I also ordered a Steam Deck for playing games that will not run on the Mac on the go, but if it can load up on the MacBook Pro - I will play it their first.
